Abstract: The secondary battery according to the present invention has a vent deformation accelerator which promotes the operation of a vent formed on a wide side of a can in the cap plate, a bottom side of a can or a narrow side of a can so that the vent operates at the low pressure. Therefore, a secondary battery is provided with a vent which operates at a lower pressure than the operating pressure of existing vents. Also, the vent can be formed relatively thick when the operating vent which operates at the same pressure as the operating pressure of an existing vent so that it can avoid forming a vent having a minute thickness, thereby reducing the manufacturing costs and processing time.

Abstract: Disclosed is a micromechanical system fabrication method using (111) single crystalline silicon as a silicon substrate and employing a reactive ion etching process in order to pattern a microstructure that will be separated from the silicon substrate and a selective release-etching process utilizing an aqueous alkaline solution in order to separate the microstructure from the silicon substrate. According to the micromechanical system fabrication method of the present invention, the side surfaces of microstructures can be formed to be vertical by employing the RIE technique. Furthermore, the microstructures can be readily separated from the silicon substrate by employing the selective release-etching technique using slow etching {111} planes as the etch stop in an aqueous alkaline solution. In addition, etched depths can be adjusted during the RIE step, thereby adjusting the thickness of the microstructure and the spacing between the microstructure and the silicon substrate.

Abstract: An electrical isolation method for silicon microelectromechanical systems provides trenches filled with insulation layers that support released silicon structures. The insulation layer that fills the trenches passes through the middle portion of the electrodes, anchors the electrodes to the silicon substrate and supports the electrode. The insulation layers do not attach the electrode to the sidewalls of the substrate, thereby forming an electrode having an “island” shape. Such an electrode is spaced far apart from the adjacent walls of the silicon substrate providing a small parasitic capacitance for the resulting structure. The isolation method is consistent with fabricating a complex structure or a structure with a complicated electrode arrangement. Furthermore, the structure and the electrode are separated from the silicon substrate in a single release step. Additionally, a metal layer is deposited on the surfaces of the structure and electrodes without using separate photolithography and etching steps.
